Now it works!
I normaly use Bluefish for file editing and even after changing:
// charset for web pages and emails
define('CHARSET', 'UTF-8');
I had the challenge mentioned above.
Now I used Quanta instead of Bluefish and I saved the file again -> and "swoops" -> everything looks like it has to.
So pls, do not ask me what makes the difference between these 2 applications -> but now it works perfectly.
